VietAlpha French–Vietnamese Mathematics Dictionary

Research page · VietAlpha Lab

The VietAlpha French–Vietnamese Mathematics Dictionary is a machine-readable edition of Danh-từ Toán-học Pháp-Việt, compiled in Saigon in 1964 by the Mathematics Committee of the National Committee for the Compilation of Specialized Dictionaries. The release contains 4,095 dictionary entries and a 1,369-item Vietnamese index reconstructed from the printed volume.

This dataset records how a Vietnamese scientific institution named mathematics in French and Vietnamese at a specific point in history. It places that record in formats that researchers can search, inspect, cite, and reuse.

Dataset contents

Component	Count	Source pages
Headword entries	1,769	16–188
Subentries	2,326	16–188
Dictionary entries	4,095	16–188
Vietnamese index items	1,369	190–228
Index references	1,879	190–228

The dictionary contains 1,716 unique headwords and 1,689 unique French lemmas. Every one of the index's 1,879 references resolves to a stable dictionary entry identifier.

Headwords and subentries are separate records. This preserves the printed hierarchy while keeping every row addressable. Numbered Vietnamese senses are also available as structured arrays when the source entry contains them.

  ]
}

An index record links a Vietnamese term back to one or more dictionary entries:

{
  "term": "Đại-số-học",
  "refs": [
    {"section": "A", "number": 116, "entry_id": "A0116"}

Use cases

French–Vietnamese mathematical terminology lookup
Historical lexicography and terminology research
Search and indexing across digitized Vietnamese mathematical texts
Dictionary-guided OCR correction for historical documents
Glossary retrieval for translation systems
Vocabulary audits for multilingual models and tokenizers
Comparison of historical and current Vietnamese mathematical usage

The release is a lexical resource. Its scope covers terms, definitions, subentries, senses, and index links.

Limitations

The dataset comes from OCR and structured reconstruction. Researchers quoting an entry should verify its wording against the cited source page. Historical spelling and punctuation remain part of the record.

Index references that could not be linked to a reconstructed dictionary entry, and index lines whose Vietnamese term was not compatible with OCR, were removed from this release rather than published with unconfirmed links. Every remaining reference resolves. The original index line text remains available in each record for inspection.
